Observe the following species $\mathrm{AlCl}_3, \mathrm{NH}_3, \mathrm{H}^{+}, \mathrm{Co}^{3+},-\mathrm{OH}, \mathrm{H}^{-} \mathrm{Mg}^{2+}, \mathrm{BF}_3, \mathrm{Cl}^{-}$ How many Lewis bases are present in the above list?
  1. 2
  2. 5
  3. 4
  4. 3

Solution

Lewis bases (electron rich) $=\mathrm{NH}_3, \mathrm{OH}^{-}, \mathrm{H}^{-}, \mathrm{Cl}^{-}$ Lewis acids (electron deficient) $=\mathrm{AlCl}_3, \mathrm{H}^{+}, \mathrm{Co}^{3+}, \mathrm{Mg}^{2+}$, $\mathrm{BF}_3$
